To al?, whom, t may concern:

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Candy-Pulling Machines, of which the following is a specification.

This invention relates to candy-pulling machines of the general class in which a plurality of grabs or pulling-arms are operated in relation to each other, so asfto draw and lap the candy, and thus by continuous operation during a sufficient period of time bring the candy to the required condition `and consistency.

In the drawings accompanying and forming a part of this speciiication, Figure 1 is a front elevation of a machine made in accordance with my present invention. Fig. 2 is a side elevation of said machine as seen from the right 'hand in Fig. 1. Fig. 3 is a plan view of the machine. Fig. 4 is a perspective view of one of the minor details. In Figs. 2 and 3 some parts of the framework are shown broken away for more clearly illustrating some features of the mechanism in the form and arrangement thereof which is illustrated in the drawings. Figs. 5, 6, 7 and 8 are diagrammatic views illustrative of the mode of operation of the pulling-arms in the operation of drawing and folding the mass of candy.

Similar characters of reference indicate like parts in all the drawings.

The object of the present improvement is to furnish a candy-pulling machine adapted for pulling and lapping the candy in a highlyefficient manner, and for this purpose I have provided a mechanism with an organization of four arms arranged in two pairs, of which one pair is arranged to revolve and the other pair is arranged to reciprocate toward and from each other and toward and from the axis of the revolving pair of arms. By means of this organization I provide a mechanism in which the candy is pulled, as indicated in Fig. 5, by three long pulls, and when these are fully drawn out, as in Fig. 6, they are then lapped over each other, as indicated in Fig. 7, with a long central lap. The further revolution of the revolving arms, as indicated in Fig. 8, carries the laps over on the other side to form two short-length folds, after which, as indicated in Fig. 5, the operation is repeated.

As a convenient means for carrying' the operative parts of the mechanism I have shown the framework of the machine arranged in the form of a base (designated in a general way by B) and a column, (designated in a general way by C.) rIhe column may be separate or integral with the base B. If made separate, it may be fastened thereto in any convenient or well-known manner. The upper portion of the column C is shown formed to serve as a easing for some of the details of the mechanism.

The principal features of the operative mechanism comprise a revolving' grab mechanism (designated in a general way by D) and a reciprocatory mechanism comprising a plurality of non-revolving grabs or pulling-arms located for coacting with the arms of the revolving member D and supported and adapt-` ed for having a reciprocatory movement toward and from the common axis of the re` volving arms, whereby said reciprocatory project arms 8 and 9, carrying the rotator-y pull" ing-arms 10 12, respectively. In Figs. 5, 6, 7, and 8 the path of movement of these arms is illustrated by the dotted circle 11, the direction of movement being shown by small arrows. For driving the shaft 4 it is shown provided withv a pulley 60.

The reciprocatory pulling-arms are designated by 14 16, respectively, and they are shown carried by operating arms or levers 24 26, respectively, these levers being carried by IOO shafts 25 27, supported in bearings 25 26', carried on the base portion B of the framework of the machine. The rearward ends of said shafts 25 27 are shown provided with arms or levers 29 31, respectively, being fast on the shafts and the ends of the arms being connected at 33 and 35 by some suitable connection-as, for instance, the rods 32-with a crank 6, supported in some convenient manner for operating in unison with the revolving drag D.

When the mechanism and the various details thereof are organized and arranged as above described, it will be obvious that the revolution of the wheel 60 will act, through the crank 6 and the connecting mechanism, to give the shiftable or reciprocatory arms 14 and v16 a to-and-fro movement toward and from each other, (and. also toward and from the aXial line of the shaft 4,) so that said reciprocatory arms will have a to-and-fro movement, (represented by the dotted lines 2o and 21, respectively,) as indicated in a general way in Fig. 1.

From the foregoing and a comparison of the several figures of the drawings, especially Figs. 5, 6, 7, and 8 in connection with Fig. 1, it will be observed that in the particular form of machine illustrated the revolving arms 1f) and 12 move substantially in the same path of revolution or rotation andthat the reciprocatory arms operate, respectively, with one in particular of the two revolving arms. This will appear more clearly from the said diagrammatic lviews Figs. 5 and 8, in which it will be seen that the reciprocatory arm 1 6 at the left hand in said figures always passes f uitsideof the respective rotary arm 10 ai d alternately with this movement passes inside of the opposite rotary arm 12. Likewise on the other side ofthe machine (which byreason` of the features here described may be properly designated as a duplex or double-acting machine) the reciprocatory arm 14.l which is shown at the right hand in said iigures, operates in a corresponding manner in connection with the other rotary arm 12. Said right-hand reciprocatory arm 14 passes outside of said rotary arm 12 and alternately with this movement it passes inside, not of the same arm, but of the other or opposite rotary arm 10. Thus the two reciprocatory arms have, respectively, the same kind of operation and coact directly with the two rotary arms, respectively. By means of this peculiar organization of the members which act directly upon the candy or analogous material being worked this material is subjected to the drawing actions, which eX- tend, as indicated, for instance, by comparison of Figs. 5 and 6, throughout the entire mass under treatment, and after the material has been so drawn out by the triple drafts the strands, as indicated by 34', 35, :11d 36, are first folded with a long fold, as indicated in Fig. 7, and they are immediately folded again with a short fold, as will be understood by comparing Fig. 8 with Fig. 7. By this means the material is lapped upon itself preparatory to being again drawn out ready for a further lapping', and so on repeatedly until it is subjected to a sufficient amount of treatment. From this comparison of said diagrammatic views it will be observed that the reciprocatory arm 16 always passes outside of a given rotatory arm, as 10, and that said arm 16 similarly always passes inside of the oppositely-disposed rotatory arm 12. In a corresponding manner the opposite reciprocatory arm 14 uniformly takes a position (when the corresponding rotatory arm is adjacent thereto) outside of said rotatory arm 12. (in the opposite stroke of said reciprocatory arm 14 it (in the same mannerabove noted) passes inside of the opposite rotatory arm 10. By means of this particular organizationof the system of four working arms, of which arms two of them are rotatory and two of them are reciprocatory, there being two arms of each of said kinds, the action of the mechanism is in a sense duplicated, so that corresponding pulling, folding, and drawing movements or operations are proceeding at the same time on each side of the central axis or shaft of the machine. In this respect this improved mechanism differs essentially from the other machines heretofore in use for pulling candy.

In the operation of this machine in the form and arrangement thereof which I have herein illustrated the actuating devices which connect the revolving mechanism with the reciprocatory mechanism are operable for imparting simultaneous reciprocatory movements to said two reciprocatory arms in opposite directions, respectively, and for imparting one complete double-stroke movement to each of said reciprocatory arms during each revolution of the rotary arms. As a result of this organization and mode of operation of the system of mechanism comprising two pairs of arms (one pair being rotary and the other being reciprocatory) a given reciprocatory arm always passes outside of a given rotary and inside of the opposite rotary arm. In Figs. 6 and 7 the reciprocatory arms 14 and 16 are shown outside of their respective directly-coacting rotary arms 12 and 10, whereas in Fig. l8 the reciprocatory arms are shown located inside of the opposite rotary arms, respectively. For instance, in Fig. 6 the reciprocatory arm 16 is shown located outside of the revolving arm 10 and in Fig. 8 is shown located inside of the opposite revolving arm 12.

During a complete rotation of the pair of rotary arms it will be observed that the reciprocatory arms come into such alinement that all of the arms are located substantially in a row and with the reciprocatory arms within the path of the rotary arms, this being illustrated, for instance, in Fig. 8. On the next half-revolution of the rotary arms it IOO will be observed that the reciprocatory arms similarly come into substantial alinement or into a row with the rotaryiarms, but this time on the outsiue of said path of revolution. This feature is illustrated by the diagrammatic views Figs. 6 and 7. By means of this organization and mode of operation of the pulling-arms in a system of four arms arranged in two pairs the candy is treated in a peculiar manner, it being subjected to long drafts or pulls in three strands, (see Figs. 5

and 6, above describech) then folded and lapped in long laps, and next the end portions of the folded mass being then .drawn out by short pulls and further lapped together. These features are indicated by Figs. '7 and 8.

In the operation of my improved pullingmachine the pair of rotatable or. revoluble pulling-arms are arranged to move insimilar orbital paths, and I deem it preferable to have them move in the same path-that is to say, in the same circular path-said arms being' located at substantially the same distance from their common axis of revolution. The pair of reciprocatory pulling-armsbeing located, respectively, on opposite sides of the axis of revolution ofthe rotary arms and connected with each other by suitable actuating means-- such, for instance, as illustrated in the draw-l ings-,said reciprocatory arms will then during the operation of the machine have alternate inward and outward movements toward and from each other and toward and from said common axis of revolutionof the rotary arms. On a given half-revolution of the rotary arms the reeiprocatory arms are brought toward each other and within the orbital path of the rotary arms.` On the next succeeding halfrevolution of the rotary arms said reciprocatory arms. are each carried away from the other and into a position outside of said orbital path.

By means ofmy improved candy-pulling apparatus the candy is drawn out and lapped by a process in which the entire length of the mass is drawn substantially equal throughout and the drawing is mainly accomplished by three simultaneous long pulls, the three strands being then lapped together. The result of this process is todraw the entire mass simultaneously and with a high degree of uniformity throughout the entire mass and then to lap the strands first by a long lap followed by a relatively small drawing out and a succeeding short one. This double system of lapping by long and short laps alternately is carried out on both sides of the machine at the same time in the same manner, with the result that the entire mass is drawn and lapped and again pulled out not only in a very efheient and `thorough manner, but with a high degree of speed, so that the machine operated at a given speed for a given period is adapted to treat properly a relatively large quantity of material.

In the operation of this machine the mass of candy is subjected to the operation of pulling in such manner as to draw the mass out into a plurality of strands, which are then lapped upon each other, and the ends of the mass so formed are folded over onto and just beyond the middle portion of the mass, which at the middle part thereof is then kneaded together, thereby to firmly unite or bond the strands into a relatively solid mass, where upon the drawing and lapping operations are repeated as before. rIhis novel feature results in favorably modifying the drawing' operations, since the lrneading together of the folded strands so changes these as `to secure a high degree of integrality or cohesion of the strands in the mass as a whole, with the result that when the pulling operations are repeated the flowage of the candy in the massis controlled and modified and the eflicieney of the operations are materiallyimproved. When the pulling-arms are carrying a nor mal amount of candy thereon and when i the long laps are made, as in Fig. 7, the reciprocatory pulling-arms 14 16 being' then advanced toward each other fold the ends past each other (see Fig. 8) over the middle portion of the mass and then directly knead or press the whole mass together in the middle portion thereof, thereby firmly incorporating the strands together, and so preparing them for a repetition of the complete operation.

For convenience of construction the reciprocatory pulling-arms 14: and 16 are shown carried on relatively long arms or levers 24 and 26, which have a forward-andbackward movement toward and from each other, thus incidentally giving to the said reciproeatolry arms a movement in a path of slight curvature; but it is evident that such specific features of the mechanism may be modified in various ways within the scope and limits of my present invention.
